1.7 Master/Slave Configuration
In systems that provide redundant timing sources, it is desirable to minimize the output skew between the master
and the slave’s output clocks. This can be achieved by synchronizing the slave to one of the master’s output clocks
instead of synchronizing the slave to an external reference. If frame pulse alignment between the timing sources is
required, then the crossover link should consist of a clk/fp pair.
One method of connecting two ZL30121 devices in a master/slave configuration is shown in Figure 8 where there is
a dedicated crossover link between timing cards. Any of the master’s unused outputs and the slave’s unused inputs
can be used as a crossover link.
